My bad it was the regular edition on sale earlier
Personally think it's worth spending the extra £6-7 to get the champion edition for the extra characters / DLC you get.
I have this (or at least most of it) digitally from PS Plus. But must admit I've bought it purely for the awesome box art.
Just checked and it's £20?
Champion edition with all DLC content is £6 on psn store right now
